    Need help water

    One of the motors on my challenger 230 430 2008 is fouling plugs. 215 supercharged . I trailer my boat in and out most of the time . But if I keep it in the water more than 12 hours one of the motors get water into the cylinders. not enough to hydro lock but enough to foul the plugs. I pull the plugs turn over a couple time put in new plugs and it starts right up. But if I stop for a couple mins it fouls again. Can anyone tell me how I could be getting water into the cylinders. ????? Please help My dealer say bring it in and he will fish around at $95 an hour to try and locate the problem. YUCK!!!! thank you Brian

    leaking intercooler would be the most likely cause and not that hard to pressure test in place
